WINDING APPARATUS Filed March 21, 1946 4 Sheets-Sheet 4 retested Feb. 12, 1952 UNITED STATES PATENT OFF-ICE 2mm a I Y Y 1 This invention relates to a winding apparatus, .and more particularly to a non-stop automatic transfer winding apparatus. The present application has been filed in place of my abandoned application Serial No. 468,332.

An object of the invention is to provide a machine for winding a web of paper onsuccessive cores in a continuous and automatic operation. Another object is to provide in a continuous winding operation, mechanism for automatically severing a web of paper and transferring the leading end of the severed web to another core. Yet another object is to provide in a winding machine, means for automatically severing the web of paper at predetermined intervals.

'8 Claims. (Cl. 242-58) Fig. 1 is a fragmentary transverse sectional 3 opposite end of the machine; and Fig. 6, a broken plan view of the machine or apparatus.

In the embodiment of the invention described herein, and as shown best in Figs. 1,2 and 3, a paper web iii of any suitable type is wound on cores ll, l2, I3 an I i4 on the mandrels i5, i6, I l and i8 respectiv l If desired, the paper web may also be slit longitudinally and perforated transversely in the winding operation.

The paper web III is passed between a pair of draw rolls l9 and 20 on shafts 2i and 22 respectively, the draw rolls being rotated by any suitable power means. The draw rolls I9 and 20 may be of any suitable or conventional construction and receive between them the web of paper.

From the draw rolls i9 and 23,. the web of paper passes to a bed roll 23 on the'shaft 24 and passes around the bed roll 23 in the direct on indicated by the arrows in Fig. 1 of the drawing to the feed roll 23 on the tube or shaft 23. The

bed; roll 23 may be equipped with annular circumferential grooves, such as the groove 21. and with transverse slots or grooves 28 extending; longitudinally of the roll.

Adjacent the bed roll a is a u a..." the shaft 30 carrying perforating knives 3|. The rolls 23 and 29 are so arranged with re pect to each other that the perforating knives 3| passthrough the paper web on the roll 23 and into the longitudinal grooves 28 on the bed roll 23. thereby providing spaced perforations in the paper web.

A slitting roll 32 on the shaft 33 is also disposed adjacent the bed roll- 23. The shaft 33 may be mounted on the arm 34 on the shaft 35 so that the roll 32 may be swung to and from a position of engagement with the web III on the bed roll 23.

The slitting roll 32 is equipped with an annular I slitting knife 38 which passes through the web Iii w on the bed roll 23 and into the annular groove 2'! of thebedroll 23..

Also adjacent thebed roll 23 is the feed roll 25 which receives the web from the bed roll 23. The feed roll 25 is provided with a recess 31 longitudinally'disposed with respect to the roll and with .a suction opening 33, by means of which suction may be applied-to the periphery of'.-the

.roll 25.. The roll 25 mayalso be equipped with annular circumferential grooves, suchas the groove 39, and witlrmstripper 40.

The shaft 4| carries-a turret 42 which supports the shaft or mandrels l5, I3, I! and I3 and the cores ll, l2, l3 and I4 carried thereon. The turret frame 42 is slowly rotated when the machine isin operation. Any suitable mechanism,

- such as a conventional gear drive, may be used for rotating the turret 42. I When the turret'42 isrotated, the mandrels l5, l6, l1 and I3. and the cores carried thereby are successively brought into position adjacent'the roll 23, this position being the web-winding position in which the web is 'transferred from the roll 25. to the adjacent core.

, Any suitable conventional means may be used forrotating the mandrels I5, l3, I1 and It.

A roll 43, carrying a proiecting knife 44, is disposed opposite the feed roll 25. The roll 43 is mounted on a shaft 45 which is supported'by an arm 48 rotatably mounted on a shaft 41. A dog 48, depending from the arm 46, may be enegaged by a suitable cam 49 which causes rotation of the arm 48 about the shaft 41v and shifts the roll 43 from the position shown in Fig. l. wherein the roll 43 is spaced away from the feed I assaaae the poaitionofl'imzleverstheweb onthefeed roll Ilandisreceived withintherecessfl inthe roll II.

The suction means, which communicates with thesuctionope'ningtlin theroll Il,isalsosynchronised with the movement of the roll 48 so thatwhentheweb ilontherollllissevered by the knife u, the suction means operates to secure the leading end of the severed web to the feed roll II. Suitable means may also be provided for releasing the suction means when the leading and of the severed web reaches a position adjacent the empty core, as seen in Fig. 8. The posi-. tion of the feed roll shown in Fig. 3 is the position at which the suction means may be released.

Beneath the turret 42 may be placed a container I. containing a liquid adhesive II. A roll I! on the shaft It is eauipped with annular pro- Jections N which dip into the liquid adhesive II and engage the empty core which is carried past the roll I! by the turret. In this manner, a layer of adhesive is applied to portions of the empty core before it reaches web-winding position.

For the purpose of clarity, the invention has been described up to this point by reference to Figs. 1, 2 and 8. The complete mechanism for the operation of the parts already referred to is shown in Figs. 4. 5 and 6 and a description of the parts shown in these figures will now be given.

In the construction shown particularly in Figs. 4, 5 and 6 A designates a base or frame in which the various operating parts are mounted; and A de ignates a bracket providing a journal for the shaft II on which the paper web It is carried in the form of a roll.

The main drive shaft It is mounted within the casing A for rotation and it is equipped with a drive wheel II which may be b lt-driven or geardriven, as desired. The shaft 24 extends through the casing and at opposite end of the casing from the drive wheel Ii is equip ed with a gear I! which meshes with a gear II on shaft 2|, with gear 84 on shaft 2i, and with gear ti on shaft ll. Gear M meshes with gear It on shaft 22. By the means just described. the bed roll 23, the knife drels II, it, I! and it independently of the turret shaft ll. A pulley II is mounted upon a bracket ll supported by easing A. as shown more clearly in Fig. 5. and is fixed to shaft-ll. The pulley II is driven by belt I! which also engalel thelargepulleyltcarriedbyshaftll. Bhafttl carries fixed thereto spaced pulleys l4 and ll. Pulley II is connected to a pulley ll supported therebelow on bracket II, as shown best in Pig. 4. bymeansofthebelt ll. Thebelttlalsoextends aboutthehubsorpulleysllcarriedbyeachof the mandrels II, IO, II and II. Asindicatedin Pig. 4, the pulleys ll of the mandrels II and i! are simultaneously engaged by the belt 80. As the turret shaft 4| rotates, it brings the pulleys or drums I of the succeeding mandrels into contact with the belt It. By this means, the mandrels are driven at a much faster speed and independently of the slowly-rotating shaft ll.

In order to drive the slitting roller shaft 8!. the shaft II is provided with a pulley l. and a belt Ii connects the pulley II and the pulley It on shaft Ii. It will be noted that shaft 88 is free to swing upon the pivoted arm It within the arcuate slot 02 provided within the frame wall A.

v The knife roll carried by shaft II is provided with gear OI, as shown best in Fig. 4. Gear It meshes with the pinion gear 04 which, in turn, meshes with the gear OI carried by shaft 22. Shaft II, which is pivotally mounted on the arm I, may thus swing about the pivot 41 and simultaneously be operated through the intermediate connecting gear II. The arm 41 is provided with a counterbalance weight or dog 48 adapted to be engaged at timed intervals by the cam member ll which is equipped with a roller end it. The weighted dog ll more than counterbalances the weight of the knife roll and the light gears it and t4 and tends normally to swing the knife roll I! to the upper position shown in Fig. 2. A caml'l carried by the shaft II has a raised portion adapted to engage the end of the cam shaft 0 so as to swing the dog outwardly and thus tilt the knife roll downwardly, as illustrated in l ig. 1. When the raised portion on cam 81 is retracted, the weights of the member It causes the arm 48 and roll 43 to swing upwardly -to the position shown in Fig. 2.

roll ll, the feed roll fl. and the draw rolls it and 20 are driven. v

Means are also provided for rotating the turret ti and the mandrels Ii, ",1"! and II. In the illustration given, the shaft 24 is rovided with a worm I! meshing with a worm gear ll mounted on the cross shaft II. The cross shaft II is shown supported mainly by a bracket member I. carried by casing A. A pinion gear II is carried by one end of the cross shaft II and meshes with bevel gear 12. The gear I! is fixed upon shaft ll mounted within casing A, and at its opposite end carries the gear 14. Gear I4 drives through the pinion II, as shown more clearly in Fig. 5, the large gear it having spokes il connecting it with a hub It fixed to shaft 4|. The turret shaft II is therefore directly driven through the gear connections described by the main shaft 24.

Meansareprovidedalsofordrivingtheman- Any suitable means may be provided for supplying suction to the passage II in the roll II. In the illustration given, a suction line It, from any suitable source of suction. leads to a casing ",as shown best in Fig. 4. The small passage or chamber within it communicates with a slot extending through the pipe 20 and roll I! so that there is open communication between the pipe ll, the passage within casing it, and the slot through the members 25 and II during the portion of the movement of the roll 25 in which the passage II is in engagement with the paper web II. The pipe or cylinder 28 is closed at each end with a cap ill, as illustrated best in Fig. 4.

In operation, the rotation of the draw rolls II and It moves the web It between these rolls. from whence it passes to the bed roll II. The rotation of the rolls 29 and 32 in conjunction with the bed roll It forms spaced transverse perforations and longitudinal slits in the paper. The slitted perforated paper passes from the bed roll 23 to the feed roll 25 and thence, as seen in Fig. l, to the paper core I I on the mandrel II.

The turret 42 may rotate slowly and continuously in the direction indicated by the arrows in Fig. l and as the winding of the web it on the core I! is completed, the core It. on the mandrel II will be shifted to the and the core I: on the mandrel II will be shifted to web-winding position as seen in Fig. 1. At this point, the cam 49' is actuated to shift the roll ll toward the roll so that the knife 44 engages the web in and severe the web on the roll 25. The suction applied through the opening 38 secures the leading end of the severed web to the roll 25 until the leading end of the web engages the empty core 12. At this point, as seen inFlg.

empty core ll onthe mandrel l5 will have been shifted to web-winding position, and the same operation of severing the web and applying it to the empty core will occur.

The adhesive, which is applied to the empty core as it passes the roll 52, serves to secure the leading end of the web to the core when the end is brought into engagement therewith. The annular projections 54 on the roll 52 are engaged in alignment with the annular recesses 39 in the feed roll 25 so that no adhesive from the core will engage the feed roll 25.

As seen particularly in Figs. 2 and 3, the knife I is received within the recess 31 of the feed roll 25 and thenmoves out of the recess as the roll 43 continues to rotate and is shifted'away from the feed roll 25. As illustrated in Fig. 3. the roll 43 is shifted back to its original position after-the web is severed.

With this device, the web I0 is fed. continuously into the machine and is automatically transferred from one core to another in the winding operation. The entire operation is automatic and the winding is continuous.

Although the invention has been described in connection with a particular embodiment, it will be apparent that many modifications and changes-may be made without departing from .second mandrel into web-winding position, a
